Symptoms of cyclosporiasis
Cyclosporiasis, caused by the microscopic Cyclospora parasite, can be contracted by ingesting contaminated food or water. It is not usually spread from person to person, according to the CDC.
Symptoms, the most common of which include frequent watery diarrhea, weight loss, appetite loss, nausea, fatigue and bloating, usually begin around one week after someone is exposed, though onset can occur two to 14 days after being exposed, according to the CDC. "Less common symptoms" include low-grade fevers and vomiting.
If untreated, symptoms of the disease can "follow a remitting-relapsing course," lasting from a "few days to a month or longer." Though illness can be "severe," it's not usually life-threatening, says the CDC.
